What Are Billable Hours?
Billable hours are the hours you spend working on tasks directly related to a client project. These are hours you invoice for. Non-billable hours, on the other hand, include admin work, marketing, invoicing, and other tasks you can’t charge your client for directly.
Why It Matters
Not tracking billable hours accurately can lead to undercharging, scope creep, and burnout. By keeping a close eye on your time, you can:
- Invoice accurately
- Understand project profitability
- Set better project rates
- Make smarter business decisions
Methods for Tracking Billable Hours
1. Manual Tracking
You can track hours manually using a spreadsheet or a physical notebook. While this can work for small projects, it's time-consuming and error-prone.
2. Digital Timers
Use a digital timer (like a Pomodoro app or stopwatch) and record the time spent per task. This is slightly more efficient but still requires manual data entry.
3. Time Tracking Tools
The most efficient method is using a dedicated time tracking tool like Time 'N Track. These tools:
- Let you start/stop timers with one click
- Categorize time by project/client
- Automatically generate timesheets
- Help you prepare invoices based on tracked time
Best Practices for Accurate Time Tracking
- Track in real-time: Avoid logging time after the fact. Memory is unreliable.
- Use detailed task names: Instead of "design," write "design client X landing page."
- Review daily: Spend 5 minutes reviewing your entries at the end of the day.
- Separate billable vs non-billable: This gives you insights into where your time really goes.
Turning Tracked Hours into Invoices
Once you’ve tracked your time, the next step is invoicing. Tools like Time 'N Track can help you:
- Generate invoices automatically
- Attach timesheets for transparency
- Set hourly or flat rates per project
